An important technique that relies on hybridization of complimentary nucleic acid sequences is Fluorescent In Situ Hybridization or FISH. This technique makes use of fluorescent probes to detect and locate specific DNA sequences in cells and tissues. In human genetics, FISH is commonly used to analyze chromosomal contents of cells and to detect [...] Continue Reading…

  The Polymerase Chain Reaction, or PCR, is a crucial method for exponentially increasing the amounts of a specific DNA sequence. PCR is a cyclic process controlled by the temperature of the reaction mixture.   First, the temperature is raised to 95C [...] Continue Reading…
